Rock Bottom

Effects

• Upon pickup and from then onwards, locks attributes to their highest values reached.
  • This applies to everything that alters Isaac's attributes, including temporary buffs from activated items and pickups. This also makes him immune to any stat downgrades.

Notes

• Health downs do not count as stat downgrades for Rock Bottom.
• Isaac's stats are still calculated normally behind the scenes, only their effective values are locked to their highest point. This means picking up an item such as Soy Milk with a severe damage penalty will make it difficult to reach a higher damage stat.
  • For example, using The Book of Belial to gain +2 damage will stay in effect indefinitely, but while it's not currently activated, Isaac must earn more than +2 damage from other items to see a difference.
  • To best utilize Rock Bottom, the player should gain as much of a single stat as they can in a single room. For example, if a player finds a Strength card and a Devil card, using them in the same room will provide a larger permanent damage boost then if they were used in separate rooms.
  • If the player finds an item that lowers a stat, such as Soy Milk, it may be beneficial to not take the item immediately. Instead, it's best to explore the floor for any potential damage ups, then take the stat-lowering item.
• If Rock Bottom is removed, Isaac's stats will no longer be locked, and return to match his current items/effects.

Synergies

Refer to the articles on Damage, Tears, Range, Shot Speed, Speed, and Luck for lists of items granting otherwise temporary boosts.

• 20/20 / The Inner Eye / Mutant Spider: Multiple tears will be shot without the items' respective stat downgrades. The damage and tear multipliers will still affect future stat ups.
• (Azazel's Stump) Azazel's Stump: Isaac will keep Azazel’s base stats after transforming back. This includes 1.25 base speed, +0.5 tears per second, and a 1.5x damage multiplier. The tear delay multiplier will not be given, including while Isaac is Azazel.
• Berserk! +3 flat damage and +0.4 speed last indefinitely. Will also give a tears up if (½ tears fired per second + 2), unless Isaac’s tears fired per second is already 4 or higher.
• Brimstone / Chocolate Milk / Monstro's Lung: Charged shot can be fired at Isaac’s normal fire rate.
• (VII - The Chariot?) VII - The Chariot?: Permanently gives Isaac a gigantic tears up.
• Clicker: will keep stat bonuses from items removed, and will retain the best stats of all characters that are cycled through.
• D8 / (Cracked Dice) Cracked Dice: Only the highest multipliers received from the D8 will be applied to Isaac. With repeated use, a 1.5-2x stat multiplier can be applied to Isaac’s speed, tears, range, and damage.
• (The Forgotten) The Forgotten / The Soul: Allows transfer of stat-ups between the two. For example, collecting Ipecac as The Forgotten doesn't give him the +40 damage boost, but it does give it to The Soul. Switching to the Soul, then switching back to the Forgotten prevents him from losing the +40 damage.
• Ipecac: Gives Isaac a massive damage up without the tears down.
  • Ipecac + Brimstone / Tech X: If Ipecac is taken before Brimstone / Tech X, its full damage up is applied to the beam/ring properly, but if the order of the items is reversed, Ipecac will only give +2 damage.
• (Jacob and Esau) Jacob and Esau / (Tainted Lazarus) Tainted Lazarus: Only the character that has Rock Bottom will be immune to stat downgrades.
• Jupiter: The +0.5 speed boost becomes permanent, turning Jupiter into a +0.2 speed up. Farts made while moving still must be charged by standing still.
• Kidney Stone: Permanently gives Isaac a x6 fire rate multiplier after firing a kidney stone. Accuracy penalty from firing kidney stones is unaffected.
• Libra: Stat balancing applies after Rock Bottom.
• Soy Milk: Gives Isaac the full tears up while keeping his previous damage; however, Soy Milk's damage divider still applies to any future damage increases.
